摘要： Techniques are provided for creating object-oriented materialized views. The object-oriented materialized views may be object materialized views or object-relational materialized views. The base tables may be object tables, object relational tables, or relational tables. The object-oriented materialized views may be refreshed, fully or incrementally. When an object-oriented materialized view is created, refresh code is generated for it. Through the use of object-oriented materialized views, users gain both the efficiency of materialized views and the power of the object-oriented paradigm.

摘要： Methods and apparatus for enabling a plurality of table columns arranged to be associated with large objects (LOBs) to share a single LOB data segment within a database are disclosed. According to one aspect of the present invention, a method for allocating space associated with at least a first column arranged to accommodate LOB data and a second column arranged to accommodate LOB data includes allocating a first LOB data segment. The method also includes associating both the first column and the second column with the first LOB data segment.

摘要： Methods and apparatus for efficiently storing data in a variable array (VARRAY) of a database system are disclosed. A method for storing data in a VARRAY having an associated large object segment in a system having a memory and a kernel includes determining a size of data to be inserted into the VARRAY. The method also includes determining when the size of the data is less than a threshold value, and storing the data as inline raw data in a column of the VARRAY that is present in the memory when the size of the data is less than the threshold value. When the size of the data is not less than the threshold value, the data is stored in a large object that is associated with the VARRAY. Further, when a VARRAY type is evolved to have a larger maximum size, existing data is not migrated or transformed.

摘要： A request to execute a query is received in a database system. In response, the database system determines that a collection of data elements to be returned by the query corresponds to a first data structure not defined within a type dictionary of the database system. The database system obtains attribute values that describe respective data fields within the first data structure, and records, within the type dictionary, a first data type definition that specifies the data fields described by the attribute values.
摘要翻译：在数据库系统中接收到执行查询的请求。作为响应，数据库系统确定要由查询返回的数据元素的集合对应于在数据库系统的类型字典内未定义的第一数据结构。数据库系统获得描述第一数据结构内的相应数据字段的属性值，并在类型字典内记录指定由属性值描述的数据字段的第一数据类型定义。

摘要： Techniques are provided for processing, within a database server, a database statement, where at least one subtask required by the database statement is to be executed in parallel by a slave set. The database server determines whether the database statement includes an external expression, relative to the subtask, that (a) produces information that is required by slave processes in the slave set in order to perform the subtask, and (b) is not to be evaluated by each slave process in the slave set. During execution of the statement, if the database statement includes an external expression, then one or more external values are generated by causing the external expression to be evaluated, and the one or more external values are communicated to slaves of the slave set to allow the slave processes to perform respective portions of the subtask in parallel, without requiring each slave of the slave set to evaluate the external expression.
摘要翻译：提供技术来在数据库服务器内处理数据库语句，数据库语句所要求的至少一个子任务将由从属集并行执行。数据库服务器确定数据库语句是否包含相对于子任务的外部表达式，（a）产生从属集中的从属进程所需的信息以执行子任务，并且（b）不被评估由从设备中的每个从属进程。在执行语句期间，如果数据库语句包含外部表达式，则通过使外部表达式进行求值来生成一个或多个外部值，并将一个或多个外部值传送到从设备的从站，以允许从属进程并行执行子任务的各个部分，而不需要从属集的每个从属点来评估外部表达式。

摘要： Systems and methods that provide for a canonical representation in a structured form of a query, against a data model platform. A parser component can parse the SQL query to generate the abstract class that represent the query (command tree). Moreover, a view generation component can supply a mapping between a rich structure (e.g., on the client side) and the relational side. Accordingly, a query can be represented by an abstract class in form of a tree structure with nodes, which has metadata tied therewith.
摘要翻译：针对数据模型平台提供查询结构化形式的规范表示的系统和方法。解析器组件可以解析SQL查询以生成表示查询（命令树）的抽象类。此外，视图生成组件可以提供丰富结构（例如，在客户端侧）和关系侧之间的映射。因此，查询可以由具有节点的树结构的形式的抽象类表示，其具有与之相关联的元数据。
